    We are wanting to have cellulose blown into our wall in our 100 year old farm house. We are chosing between two different installers. One will drill a hole half way into the underside of the siding and tube fill the walls. The other installer said he will use the “double-open” method drilling a hole on the underside of the siding at the top and bottom of the walls. Can you tell me what method is recommended? Thank you!

    We had Cellulose insulation blown into our attic in Sept. of 2013. I was doing our taxes and it is recommented to have the manufacturers certification statement. Is this something we can get from you or do we need to contact our contractor. We would like to be able to access the credit for our taxes. Thanks for your time and assistance.

    I am looking for cellulose sound proofing panels……1/2″ x 4′ x 8′ panels in particular. How much am I looking at cost-wise. I need 12 panels.

    thanks man!

    Hi we are looking to replace our insulation. I have a questions in regards to cellulose insulation, what is the boric acid content if any? Those it have any product that helps with pest control ?

    • CIMA Admin says:

      Thanks for your question. Cellulose insulation is not a generic material so borate content is brand specific. It will generally range from 5% to 15% by weight. There are two brands of cellulose insulation that are registered by the EPA as approved pest control products. They are InCide and T.A.P.

    I was told by a termite that the cellulose insulation on the concrete walls under my house attracted termites. Is that true

    • CIMA Admin says:

      Your termite company is mistaken. Cellulose insulation uses borate fire retardants, which are unattractive to insects. So the product would not attract termites or any other insect. In fact, there are even some cellulose insulation brands available that are certified pest control products.

  6. Glenda says:

    Should have said termite company. I do not really talk to termites?

    I read the great article about cellulose in the new Fine Homebuilding magazine. Where can I get boric acid only cellulose for my project in the Lake Tahoe CA area? Thanks!

    i have an old house feels colder all the time even after heat runs all day
    need an estimate please

    Thank you for writing about “Summer Home Energy Savings Tips” on The Greenest Of The Green’s website:

    I’ve been looking for some resources about green living online – I’m glad your website has info that could be useful to people looking to reduce their impact on the environment. We at Coupon Chief recently published a huge guide about inexpensive ways to go green. It includes up-to-date information and special tips to help people adopt a more Earth-friendly lifestyle without draining their wallets.

    Thought you might be interested in seeing it. Can I send you the link to the guide for potential inclusion in your list of resources?

    Hoping to hear from you!

      Your guide missed one of the best ways to reduce environmental impacts…using Cellulose Insulation. It’s over 80% recycled material, has the lowest embodied energy of insulation products and is an affordable way to reduce home energy bills and greenhouse gases.

  10. Bob Feinstein says:

    Tornado destroyed garage roof and blew cellulose ceiling insulation all over the yard. Will the insulation biodegrade now that it is exposed to elements? About 3 acres of yard. Any suggestions to ease cleanup?

    • CIMA Admin says:

      Cellulose insulation will biodegrade when exposed to the elements, just as the cellulose in hydromulch does over time. The potential problem is that boric acid used for fire retardant is a mild herbicide. It can kill grass where enough of it piles up. If spread lightly over a very wide area it may be okay. Probably best to at least run a lawn vacuum over the yard to be safe.

  11. Michael Drehl says:

    I know even with dense packed cellulose in the walls, it will settle because of building movements.
    Will that cause any problems for even 1/2 inch of settlement in the walls? Like moisture issues?

    • CIMA Admin says:

      Thanks for the comment and question. Your assumption is not correct however. When cellulose insulation is packed in a wall cavity at 3.0 to 3.5 pcf it is essentially spring loaded in the cavity. Assuming proper installation we would not expect the insulation to settle. Should settlement occur due to inadequate density (ie: improper installation) the problem would be loss of thermal performance due to greater air infiltration and an insulation void at the top of the cavity. Thanks
